(1) The result of PID operations, which are performed based on the measured value,
is stored.
(2) The stored value differs depending on the control mode. For control modes, refer
to Control mode monitor (buffer memory address: 30) and Control mode (buffer
memory address: 50, 82) (Section 3.5.9 and 3.5.23).
The following explains the value to be stored for each control mode.
(a) Normal control mode, manual control mode 1, and program control mode
The value to be stored is in the range of -50 to 1050 (-0.5 to 105.0%). The
manipulated value (MV) is the rate (%) against the full scale (16mA) of the
output range (4 to 20mA). The output value is 4mA for 0%, 12mA for 50%, or
20mA for 100%.
(b) Manual control mode 2
The value to be stored is in the range of 0 to 4000. The manipulated value
(MV) is the digital output value corresponds to the output range (4 to 20mA).
The output value is 4mA for 0, 12mA for 2000, or 20mA for 4000.
(1) This flag checks if the measured value (PV) is within the approach band.
(2) When the measured value (PV) is within the approach band, the flag is set to 1.
If Approach soak time setting (buffer memory address: 168) is set, the flag is
set to 1 when the measured value (PV) stays within the approach band only for
the set period of time.
(1) The current set value is stored.
When Setting change rate limiter (buffer memory address: 52, 84) is set, the
transitional change of the set value during the program control is monitored.
(1) The measured temperature of cold junction temperature compensation resistor
mounted on the Q62HLC is stored.
The value to be stored is in the range of -20 to 100 (-20 to 100 ).
